Does anyone know what type of fuse/resistor is being used on the reverse signal line? I have power on one side (the side being provided w/power) but not the other side that leads to the head unit. So i need to replace it but with what?

Thanks for any help!

I thought it was a resister, but was corrected by a sales rep for Pioneer. He said it was a fuse.

A customer wanted me to hook up the reverse wire, but he lost the fused wire. I asked the sales rep if he had a spare or if it was necessary. He said it was a fuse and gave me one out of a returned AVIC he had.

I have never tested to make sure it is a fuse or opened it up to confirm. Makes sense if it is a fuse because backup lights do tend to short out over time on some cars.

it is actually a "fuse resistor" i took mine apart. I have no idea what the rating for the resistance or fuse is. I am currently not using it. i have my reverse wire hook directly up to a 12 v source. It has been working flawlessly for many months, so i am going to go ahead and say you don't need it, but someone correct me if i am wrong.
